Similar issue I have inherited a pyronix system with a low battery in the siren that keeps setting off the panel. I don't have a ladder that can reach the siren to change the battery and it's an old system that does not give notifications it just makes noise! Alarm company won't share the engineers code. I'd considered pulling the fuse and battery out of the main console but the siren will likely go off. What's the best way to shut it all down or at least stop the alarm sounding because of the low battery without changing the battery?
